Notice the changing diameter of the Moon during
the 'moonth'. As the Moon's orbit brings it
closer to earth (perigee) at the New Moon, it
appears larger to us. Also notice how the Moon
'rocks' up and down and back and forth. That
happens because the Moon's orbit takes it above
the Earth's equator (allowing us to see more of
the south polar region) and below the equator
revealing more of the north polar region of the
Moon. The back and forth (east-west) rocking is
due to the changing orbital velocity of the moon.
